Beginners notice everything because nothing is normal yet. Keep a little beginner in you.

When everything is new your brain has no shortcuts yet, so it actually looks. A few months in the shortcuts arrive and looking gets quietly replaced by assuming. That is why your first day somewhere hands you observations you never get again, and why someone who has done a thing for years can miss what is obvious to the new kid. Familiarity is efficient and a little blind.

Pick something you do on autopilot and do it slowly once this week. Ask the question you think you already know the answer to.
